Surround sound uses multiple speakers to create an immersive experience. What's the 5.1, 6.1, or 7.1 mean? It's the number of speakers plus one subwoofer.
The sub gives you that rumbling bass sound. Keep in mind some subs are better for home theater than music and vice versa.
A home-theater-in-a-box (HTIB) system puts all the components for surround sound in one box with easy setup instructions.
